Title: Improvements in stop-cocks
IPC: F16K3/26
Filed: 1928-03-07
Abstract: 298,852. Schõffer & Budenberg Ges. Oct. 18, 1927, [Convention date]. Closure members, piston and tubular; leakage, preventing. - A tubular plug 1 working in a perforated shell 2 is flanged to engage a flange 2a at the lower end of the shell thereby compressing packing 3 when the valve is closed. The valve spindle 4 is in screw threaded engagement with a loose sleeve 9 held from rotation by lugs 10 within the casing 7, so that in closing the valve the upward thrust on the sleeve compresses the stuffing box packing 8 around the spindle. The resilience of the packings keeps the shell 2 and sleeve 9 in contact when the valve is open.

Title: Recording information from a document
IPC: G06K15/10
Filed: 1976-02-24
Abstract: 1527917 Magnetic recording using bubble domains INTERNATIONAL BUSINESS MACHINES CORP 24 Feb 1976 [26 March 1975] 07139/76 Heading B6C A magnetic image on a document is recorded by placing the document against a magnetic bubble domain material and causing the collapse of bubbles in the image areas under the action of a bias field. The document generally carries a magnetic ink image, and the image formed in the bubble domain material may be shifted out electronically to storage or to a utilization device or may be developed with toner and transferred to a copy sheet. In the embodiment of Fig. 1 plate 7 has an array of bubbles uniformly distributed therein by coils 12a, 12b; a document 9 having magnetic ink areas 9a is fed in from hopper 2 and is pressed against plate 7 while a bias field is maintained by elements 10a, 10b. Since the magnetic bubbles are sensitive to the strength of the applied field those bubbles immediately under areas 9a collapse. Plate 7 is lowered and document 9 fed from the apparatus. The image is shifted from bubble plate 7 along cable 8. In an alternative embodiment, Fig. 3 (not shown), document (53) is fed between a bias field drum (51) and bubble material on drum (52), thus enabling a lineby-line scan of the document. Toner is applied to drum (52) or station (56) transferred to copy sheet (55) and residual cleaned off at station (59).

Mechanism for removing a casting from a mould comprises a hoist movable towards and away from a position over the mould and comprising an upper support 38, 39, a lower support 40, a spring 43 urging the lower support upwardly, a member secured to the lower support and engageable with the head of a screw 13 cast in the casting, a handwheel 44 rotatably mounted on the lower support 40 and dogs 58, 77 connected respectively to the lower support and the handwheel, whereby the handwheel may be turned to disengage the screw and casting, the spring 43 upwardly retracting the screw, the handwheel and associated structure as the screw disengages the casting. When lifting the ingot from the mould, its weight compresses the spring 43. The hoist is then moved on a monorail to an unloading position and the ingot lowered to the floor, the spring being maintained compressed. Rotation of the handwheel unscrews the screw 13, and as it moves out of the casting, the handwheel and associated mechanism are moved upwardly by the spring. The ingot may be cast with more than one screw embedded therein, and a corresponding number of hoists used to extract it. The screw is initially loosened in the casting by, if necessary, oscillating the handwheel so as to impact dogs 77 upon dogs 68.
